Question
Physics Question on Electromagnetic induction
An electric motor converts electrical energy to mechanical energy The working of the motor is based on mutual induction
A
If both assertion and reason are true and reason is the correct explanation of assertion
B
If both assertion and reason are true but reason is not the correct explanation of assertion
C
If assertion is true but reason is false
D
If both assertion and reason are false
Answer
If both assertion and reason are false
Explanation
Solution
A dc motor converts electric energy into mechanical energy. The principle on which it is based is not mutual induction. A current carrying coil, in a magnetic field experiences a torque. This torque rotates the coil. The dc motor is based on the interaction of current and magnetic field
